Interesting, that works. I would have thought setting it in
the repo.conf would have worked too, though.
So, can I have one (1) repo.conf and use it for multiple ABIs,
like so?:
$ cat /usr/local/etc/pkg/repos/FreeBSD_10x.conf
FreeBSD_10x: {
url: "pkg+http://pkg.FreeBSD.org/${ABI}/latest
mirror_type: "srv",
signature_type: "fingerprints",
fingerprints: "/usr/share/keys/pkg",
enabled: yes
}
$ mkdir /tmp/10x_amd64
$ mkdir /tmp/10x_x86
$ pkg fetch -Ud -r FreeBSD_10x -o /tmp/10x_amd64 \
security/sudo shells/bash
$ pkg -o ABI=freebsd:10:x86:32 fetch -Ud -r FreeBSD_10x \
-o /tmp/10x_x86 security/sudo shells/bash
I suppose this assumes that the package dependencies are exactly
the same for all the ABIs that one would need.
